Abstract

A 16 × 1‐element microstrip antenna array with dual‐polarized stacked corner‐fed square patches as its elements is presented. This linear array fed by the coplanar feed and the slot‐coupled feed for dual polarization, respectively, together with the pair‐wise anti‐phase feeding technique, achieves measured port isolation better than 33 dB with the maximum reaching 43 dB in the bandwidth of 9.375–9.825 GHz. The measured bandwidths of VSWR ≤ 1.5 reach 15% and 13.5% for the two ports, respectively, and the measured gain is better than 16.7 dB in the operating bandwidth, which are suitable for synthetic aperture radar (SAR) application. © 2005 Wiley Periodicals, Inc.
